NEWTOWN, Conn.  An official with knowledge of the situation says a gunman at the center of a school shooting in Newtown, Conn., has been killed.

The official who spoke on condition of anonymity because the investigation is still under way says the man apparently had two guns.

A dispatcher at the Newtown Volunteer Ambulance Corps says a teacher has been shot in the foot and taken to Danbury Hospital, but it's unclear whether there are other injuries.

Ambulance surrounded Sandy Hook Elementary School in western Connecticut and parents were running toward the building as a helicopter flew overhead.

The superintendent's office says the district has locked down schools.

State police say Newtown police called them at about 9:40 a.m. about the shooting reports.
